yiN!PRO7VIMNT IN ORE-SEPRATRS.

To all whom it may concer-n:

Be it known that I, J oHANN FRIEDRICH UTSCH, of Iserlohn, Germany, have invented a new and Improved Self-Acting Jig-Machine, of which the following is a specification:

In the accompanying drawing, Figure l is a vertical longitudinal section of my improved jig-machine; Fig. 2 is a top view of the same; and Fig. 3 a vertical transverse section.

The lines c cand 7a 7s in Fig. 2 indicate, respectively, the planes of section for Figs. l and 3.

Similar letters 0I" reference indicate corresponding parts.

This invention relates to a new self-acting jig-machine, in which separate chambers,hav ing separate discharge-openings at varying heights, are arranged for the recept-ion ofthe several kinds of ore, salts, or other material which are `to be separated from one another by virtuel of their varying specific gravity.

'By having the said chambers so united as to permit a free flow of the ore from one to another the process of separation is greatly facilitated, and the separation carried on with greater certainty than in the jig-machines now in use.

In the accompanying drawing, the letter A represents the case or box that constitutes the jigmachine. Init is a longitudinal partition, a, crossing two or more transverse partitions, b d. The transverse partitions extend from top to bottom of the vessel A, as shown in Fig. 1, while the longitudinal partition a, shown in Fig. 3, does not reach to thebottom. On one side of the partition c are arranged the several series e, f, and g, that serve as supports for the ore to be separated. On the other side of the partition a are plungers el, f1, and g1, moved up and down by eccentrics hon a shaft, B, or by other suitable means, to force the Water up through the sieves and agit-ate the ore thereon. The iirst sieve, e, is

l higher than f2, and this again higher than g2.

The ore being fed to the rst sieve e, and

agitated by the Water, arranges its parts to` have those of lighter gravity on top and the heavier atthe bottom. The lighter quality will then immediately iiow oft' through the aperture e2. to the sieve f, Where the heaviest again settles to the bottom,the rest passing oft' through f2. Finally, the heaviest ore having reached vthe sieve g escapes through the opening g2.

When the number of subdivisions are to vary, the number of sieves and discharge-openings must vary accordingly.

Whenever it is desired to dispense with the slotted partitions above the sieves there will be but one chamber With several dischargeopenings -at varying heights. In that case, however, I would prefer to have but two openings to one single chamber.

In every case the apparatus will be entirely self-acting. Even when no partitions are used the ore will, owing to the settlement of its parts in accordance with their speciic gravity, discharge its several constituents through the several openings only, and this without attention, quite automatically.

When the ore is applied without the in gredient for which the highest discharge-opening is calculated, the discharge will take place through the remaining openings with' equal promptness.

In this connection I will state that the varying heights of, or vertical distances between, the several discharge-openings are calculated in accordance with the ascertained difference in specic gravity of the constituents to be acted upon, as otherwise the subdivision of ingredients would not take place with the necessary exactitude.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The partitions b d, slotted above the sieves of an ore-separator to allow the convenient passage of ore from one sieve to another, as specied.

2. The several discharge-openings arranged at varying heights above the sieve or sieves of a jig-machine, in conformity to the variation between the specific gravity of the materials to be separated, as set forth.
